Does ISO 14064-1 use scope 1, 2 and 3?

No. The word scope does not appear in the body of the document. It occurs once, in the bibliography, inside the title of the GHG Protocol standard cited as a reference. The standard organizes the inventory into six categories and publishes no correspondence table with the three scopes.

Where do leased vehicles belong?

It depends on your consolidation approach, and Annex B says so through an example: if you use operational control, fleet emissions are reported as direct; if you use financial control, as indirect. In that second case the standard leaves the choice between the transportation category and the products used category.

Does purchased electricity include upstream fuel emissions?

No, and this is the most common double count. Category 2 covers only the fuel combustion associated with producing the delivered energy. Cradle to plant gate emissions, plant construction and transmission losses are excluded; upstream belongs to category 4.

Must every indirect emission be quantified?

No. You shall apply and document a process, define your own significance criteria, then quantify and report the significant indirect emissions. Excluding a significant indirect emission shall be justified. The standard adds that these criteria should not be used to leave out substantial quantities.

Does this tool provide emission factors?

No, deliberately. A factor depends on the country, the electricity mix and the year: publishing one without a dated source would be an invented value. This tool classifies your sources, it does not quantify them.

Why classification decides everything that follows

A greenhouse gas inventory is rarely challenged on its emission factors, which are public, and almost always on its boundary. A source placed in the wrong category distorts two category totals at once, and a source counted twice inflates a figure nobody will be able to reproduce. Clause 5.2.4 sets six categories; Annex B details their reporting items and flags the places where the same emission could attach to two of them. Those places are what cost, and that is where this tool stops you.

The method, in the order the standard sets

1
Set the organizational boundary and the consolidation approach
Clause 5.1 offers a choice between control, financial or operational, and equity share. The organization shall document and state the one it applies: this is not an internal setting, it belongs in the report.
2
Define the reporting boundary
Clause 5.2.1 asks you to identify the direct and indirect emissions and removals associated with your operations, and to document them.
3
Place each source in one of the six categories
Clause 6.1 is explicit: sources and sinks shall be identified and classified into one of the categories set out in 5.2.4. That is what this tool does.
4
Assess the significance of your indirect emissions
Clause 5.2.3 asks you to apply and document a process, using your own predetermined criteria. The standard mentions magnitude, level of influence, access to information and data accuracy. It sets no numeric threshold.
5
Quantify, report, and justify any exclusion
Significant indirect emissions shall be quantified and reported, and excluding any of them shall be justified.

The traps, all checked against the text

The standard never writes the word scope. Its only occurrence is in the bibliography, inside the title of the GHG Protocol standard. Reading categories 3 to 6 as scope 3 is a convention, not an equivalence the standard publishes.
Category 2 explicitly excludes upstream fuel emissions, power plant construction and transmission losses. Those upstream emissions belong to category 4, purchased goods. Counting them in category 2 counts them twice.
A leased fleet has no single answer. Under operational control, the Annex B example reports it as direct emissions; under financial control, as indirect. The question is therefore not the lease contract, it is your consolidation approach.
For leased equipment the standard says an organization using operational control may quantify these emissions as direct. May, not shall: an organization that leaves them in category 4 remains compliant.
Transport of waste to the disposal facility may be quantified with the treatment or with transport. Both are allowed, neither allows counting it in both.
A significant indirect emission cannot be waved away: excluding it shall be justified. And the significance criteria are yours, the standard sets none.

Classify your emissions under ISO 14064-1

The climate side of a CSR programme starts with an inventory, and an inventory starts with classification. Six categories, and two cases where the answer depends on your consolidation approach.
